DS really needs some brushing up on grammar. We have Shurley English, but I feel it is too much parent work for a 5th grader. What else is out there that will help booster his grammar skills and not require me to sit with him for an hour to do one lesson. I dont mind teaching him, but an hour lesson in just one subject while I need to do K with my dd and watch my toddler just is not reasonable here.
